A review of effects from exposure to static magnetic fields in magnetic resonance imaging

For its operation, MRI requires (Coskun, 2010; Crook, 2009; De Wilde, 2007; Hartwig, 2009; Marshall, 2007; McRobbie, 2012):

1. A SMF with a given field strength (from 0,2 T to 3 T in clinical use);

2. Time-Varying magnetic Field Gradients (TVGF), with a variable intensity and slew rate;

3. RF fields, which works as a transmitter and receiver system.
